Video of the incident went viral online. Now, she's telling her side of the story.

Christina Gardilcic says she never saw it coming. She says when the officer shoved her, it happened so fast, she was in shock.

"So, we were just walking on a sidewalk and the next thing I know I was just on a bench, my feet were up in the air," she remembers. "What happened to me, I consider excessive force. I had no idea I was doing anything wrong. If I was, and he physically shoved me and I fell, I could have been really hurt."

The incident happened Saturday night after University of Arizona's loss to Wisconsin in the NCAA Tournament.

Officers asked people to leave as the crowd got bigger. But, they refused and started throwing beer bottles and firecrackers at officers.

Cell phone video captures one of those officers shoving Gardilcic as she walked by. The video went viral, many calling for Sgt. Joel Mann's termination.

Mann is an 18-year veteran of the department. But, Tucson police say he's on regular duty while they investigate.

They say 50 officers were wearing body cameras and they're still reviewing more than 100 hours of video.

Gardilcic had a lot more to say about this viral video and how she was treated.
